Bo-ramahlale ba tlaleha ho theoa ha polaritons ea matter-wave ka har'a letlapa la optical, tšibollo ea liteko e lumellang lithuto tsa paradigm ea mahlale a mahareng le theknoloji ka papiso e tobileng ea palo e sebelisang liathomo tsa ultracold.
Ho sibolloa ha Matter-Wave Polaritons ho Hlahisa Leseli le Lecha ho Photonic Quantum Technologies
Patlisiso e hatisitsoeng koranteng ea Nature Physics e fana ka sethala sa "second quantum revolution".
Ntlafatso ea lipolanete tsa liteko tse ntšetsang pele lefapha la mahlale le thekenoloji ea quantum (QIST) e tla ka melemo le liqholotso tse ngata tse tloaelehileng ho theknoloji efe kapa efe e hlahang. Bafuputsi ba Univesithing ea Stony Brook, ba etelletsoeng pele ke Dominik Schneble, PhD, ba tlaleha ho thehoa ha polaritons ea taba-wave ka har'a lesela la optical, tšibollo ea liteko e lumellang lithuto tsa paradigm e bohareng ea QIST ka ho toba quantum simulation ho sebelisa liathomo tsa ultracold. Bo-ramahlale ba rera hore li-quasiparticles tsa bona tse ncha, tse etsisang li-photon tse sebetsanang ka matla ka thepa le lisebelisoa empa li qoba mathata a mang a tlhaho, li tla thusa nts'etsopele ea liforomo tsa QIST tse ikemiselitseng ho fetola theknoloji ea likhomphutha le puisano.
Liphetho tsa lipatlisiso li hlalositsoe ka botlalo pampiring e hatisitsoeng koranteng Fisiks ya Tlhaho.
Boithuto bona bo fana ka leseli mabapi le thepa ea mantlha ea polariton le liketsahalo tse amanang le 'mele e mengata, hape e bula menyetla e mecha bakeng sa lithuto tsa polaritonic quantum matter.
Phephetso ea bohlokoa ho sebetsa le liforomo tsa QIST tse thehiloeng ho photon ke hore le hoja li-photon e ka ba lijari tse loketseng tsa tlhahisoleseding ea quantum hangata ha li sebelisane. Ho ba sieo ha litšebelisano tse joalo ho boetse ho thibela phapanyetsano e laoloang ea tlhahisoleseding ea quantum pakeng tsa bona. Bo-rasaense ba fumane tsela ea ho pota-pota sena ka ho kopanya li-photon le lintho tse matla haholo tse tsosang takatso ea lintho tse bonahalang, kahoo ba etsa li-polaritons, tse nyalisitsoeng tse kang chimera pakeng tsa leseli le ntho. Likhohlano pakeng tsa li-quasiparticles tse boima haholo li etsa hore ho khonehe hore li-photon li sebelisane ka katleho. Sena se ka etsa hore ho kenngoe ts'ebetsong ea ts'ebetso ea liheke tsa quantum tse thehiloeng ho photon 'me qetellong ea lisebelisoa tsohle tsa QIST.
Leha ho le joalo, phephetso e kholo ke nako e lekanyelitsoeng ea bophelo ba li-polariton tsena tse thehiloeng ho photon ka lebaka la ho kopana ha tsona ka mahlaseli ho tikoloho, e leng se lebisang ho bola ho sa laoleheng le ho senya.
Phetolelo ea bonono ea liphuputso tsa lipatlisiso thutong ea polariton e bontša liathomo tse ka har'a letlapa la optical tse etsang karolo ea insulating (ka ho le letšehali); liathomo tse fetohang li-polaritons tsa taba-wave ka vacuum coupling tse kentsoeng ke mahlaseli a microwave a emeloang ke 'mala o motala (bohareng); li-polaritons li fetoha tse tsamaeang 'me li etsa mokhahlelo oa superfluid bakeng sa khokahanyo e matla ea vacuum (ka ho le letona). Mokitlane: Alfonso Lanuza/Schneble Lab/Univesithi ea Stony Brook.
Ho ea ka Schneble le basebetsi-'moho, lipatlisiso tsa bona tsa polariton tse hatisitsoeng li qoba mefokolo e joalo e bakoang ke ho bola ho itlelang feela ka ho feletseng. Likarolo tsa photon tsa li-polaritons tsa tsona li tsamaisoa ka ho feletseng ke maqhubu a taba ea athomo, eo mekhoa e joalo ea ho bola e sa batleheng e leng sieo. Tšobotsi ena e bula monyetla oa ho fumana mebuso ea parameter e e-s'o fumanehe, kapa e e-s'o fumanehe ka mokhoa oa photon-based polaritonic systems.
"Nts'etsopele ea quantum mechanics e atile lekholong le fetileng la lilemo, 'me 'phetoho ea bobeli ea quantum' mabapi le nts'etsopele ea QIST le ts'ebeliso ea eona e se e ntse e tsoela pele lefatšeng ka bophara, ho kenyeletsoa le likoporasi tse kang IBM, Google le Amazon," ho bolela Schneble, Moprofesa Lefapheng la Fisiks le Astronomy Kolecheng ea Bonono le Saense. "Mosebetsi oa rona o totobatsa litlamorao tse ling tsa mantlha tse khahlang bakeng sa lits'ebetso tse hlahang tsa photonic quantum ho QIST ho tloha ho semiconductor nanophotonics ho isa ho circuit quantum electrodynamics."
Bafuputsi ba Stony Brook ba ile ba etsa liteko tsa bona ka sethala se nang le liathomo tsa ultracold ka har'a lattice ea optical, e leng sebaka se kang lehe se nang le kreiti e entsoeng ke maqhubu a emeng a khanya. Ba sebelisa sesebelisoa sa vacuum se inehetseng se nang le li-laser tse fapaneng le libaka tsa taolo, 'me se sebetsa ka mocheso oa nanokelvin, ba ile ba kenya ts'ebetsong boemo boo ho bona liathomo li neng li koaletsoe ka "lattice" ka maru a vacuum a entsoeng ka maqhubu a senyehang, a fetohang.
Sehlopha se fumane hore, ka lebaka leo, likaroloana tsa polaritonic li fetoha tse tsamaeang haholo. Bafuputsi ba ile ba khona ho hlahloba ka ho toba sebopeho sa bona sa ka hare ka ho sisinya lesela ka bonolo, kahoo ba fihlella menehelo ea maqhubu a taba le ho tsosoa ha letlapa la athomo. Ha li tloheloa li le mong, li-polartons tsa taba-wave li tšela ka har'a letlapa, li sebelisana, 'me li theha mekhahlelo e tsitsitseng ea taba ea quasiparticle.
Schneble oa hlalosa: "Ka teko ea rona re ile ra etsa papiso ea quantum ea tsamaiso ea exciton-polariton tsamaisong e ncha. "Taba ea ho etsa joalo analogue’ simulations, which in addition areanalog` ka kutloisiso ea hore liparamente tse amehang li ka letsetsa ka bolokolohi, ka botsona ke tataiso ea bohlokoa ka hare ho QIST.
